Helping You Build A Better Time Machine

Each of our cables are designed to help you build a better Time Machine, and are personally hand-made to order by Chris Sommovigo, designer & proprietor of Black Cat Cable.


In 1992 Chris Sommovigo introduced the first truly precision 75 Ohm digital coaxial cable for high end audio under the name “ILLUMINATI†- legendary designs that have stood the test of time.

BLACK CAT CABLE: A small company with a limited output of specialty cables radiating from the same core ethos: each cable personally built by Chris Sommovigo to ensure that standards are maintained. We don’t produce thousands of cables per month, or provide products to hundreds of dealers … we aren’t able to meet such demands due to the highly specialized nature of our processes.

This translates to extremely high-quality cables manufactured to high standards using select raw-materials, unique processes, custom tooling & machinery, and the unmistakable touch of the inventor’s hand.



All of our cables are made to order by Chris Sommovigo, personally. Please allow 1-3 weeks for shipping.

Coppertone FLATWAVEâ„¢ Speaker Cable: Starting $299.

The Coppertone Loudspeaker cable uses tin-plated copper conductors that are loved by so many for their classic sound and arranges them in a coaxial dual-tube arrangement based on a dual-layer helical wind with braided nylon-multifilament fibers between the layers. Inside the tube is our unique FLATWAVE™ conductor,


The new Flatwave conductor is a small, pure copper ribbon that we flatten in-house with a precision rolling machine. The flattened conductor is then rolled through our Airwave tooling, shaping it into a sinusoidal form so that it will remain substantially suspended in air once hand-placed within Coppertone’s thin-walled PTFE tube. Our XOX direct-plated pure copper bananas terminate to the speaker cable for unimpeded signal transfer.

Although this is a very compact design, don’t be fooled by the size! Each pole sums to ca: 15 AWG

The Black Cat entry level Coppertone RCA interconnect and banana terminated speaker cables are simply amazing bargains.  We think they redefine the entry level high end cable price to performance ratio. ~ Fair Hedon


From a customer in Zagreb:

Good evening, To whoever might be bothered to read: I am what you – presumably – call a budget music lover. I life time vinyl collector, Detroit techno afficionado from Eastern Europe, I’ve always invested money in black wax rather than “the other stuff”. Regardless, even if when I wanted to invest in something that WhatHiFi and similar would review, or deem worth owning, it’d cost 25 records worth… Which is a no-no in my book. Plus, I am a welder in Zagreb (Croatia), so already buying records is taking food off my table, let alone accessories.

Anyways, as every person who holds their record collection dear, my dream was to provide my precious vinyl with the best possible accessories I could afford. For years, stuff like Nodost or Transparent has been a wishful thinking type of a deal for me. Watching cables cost as much as a bulk of a collection you spent years building seemed ridiculous. Anyways, Mr. Sommovigo and his products have always been there at all the festivals, all the presentations, all the you-name-it as the real, connoisseur stuff once all the hype and glamour is gone.

Well, could be, I thought, but given the fact the man sells cables at a price that exceed my yearly rent, I always thought this stuff would be something I’d always be hearing and reading about, but never touch.

Not to prolong. Today, I am a proud owner of the Black Cat speaker cable and Interconnect, the Coppertone series. I know that to you guys it might be the cheapest thing you’ve ever done, but trust me, you have finally enabled me, if even for a moment, the entrance into this “high end” world. Although I paid through the nose for it at the HD Multimedia shop, I wanted to give you all a HUGE virtual hug and a massive THANK YOU for putting out on the market something for the common man, if you so wish to put it. The cables are first league, top tier material, here’s to another few decades, and I might even move up to the more expensive ones.

Sincerely yours, Martin


From a customer in Ohio:

AWESOME CABLE!!!!  It’s earned the coveted “Eight Thumbs Up!†award.

I have 2 golden-eared audio buddies that are extremely reliable when it comes to listening and reporting exactly what they hear. My wife gets the same description.

We ALL heard the same differences when compared to my [famous cable brand redacted] that have been in place since they first came out – probably 25 years ago. As I mentioned, the [famous cables] were the highest rated interconnects at the time…but times, and cable development have moved ahead.

What differences did we hear?

In direct comparisons to the [famous cables], the Coppertones have more “air,†better transients – especially above 3khz, better defined instrument locations, and tighter bass response and decay. Better in every conceivable way, actually. I don’t even want to think what your more advanced (read expensive) cables can do …

It really is a significant improvement over my long-loved [famous cables]. I’m actually quite surprised – pleasantly, of course.

3232 Speaker Cable

Starting $649.

From a customer in New York City:

Hey Chris,


Just wanted to say thank you for the cables and that I hope you are enjoying a fantastic weekend.


… for now, feeding a Chord DAC direct into a pre-production LTA Ultralinear with volume control into even my woefully inefficient backup Spendors and the cables sound great, great, great (and are truly beautifully crafted).


My [famous name] and [exotic brand] cables don’t hold a candle to these. They just sound live. What you do is so appreciated.


Many thanks from a happy customer,

~ Alex

This is a multilayered cable that begins with a 6mm core of pure cotton rope sourced from Japan. This is central to the cable as a means of creating a core that is mechanically damped. Around the core is a braid of 32 bare, pure copper strands at 30 AWG each (summing to 15AWG), then an interstitial layer of braided multifilament nylon, a secondary layer of 32 braided copper wires – same as the interior layer of wire – and finally an overall braided jacket of nylon.
